Insights

Probiotic supplementation in infant formula altered fatty acid levels, impacting the absorption of polyunsaturated fatty acids (PUFA). This suggests a link between probiotics and PUFA metabolism in infants with eczema.

Area of Science:

  • Nutrition Science
  • Microbiology
  • Pediatric Allergy

Background:

  • Probiotic therapy shows promise for managing allergic symptoms.
  • The impact of probiotics on dietary polyunsaturated fatty acid (PUFA) absorption and utilization requires further investigation.

Purpose of the Study:

  • To examine if probiotic supplementation affects PUFA absorption and utilization in infants with atopic eczema.
  • To explore the relationship between specific probiotic strains (Bifidobacterium Bb-12 and Lactobacillus GG) and fatty acid profiles.

Main Methods:

  • A randomized, placebo-controlled, double-blind study involving 15 infants with atopic eczema.
  • Infants received infant formula supplemented with Bifidobacterium Bb-12, Lactobacillus GG, or a placebo.
  • Plasma neutral lipids and phospholipids were analyzed for fatty acid proportions, specifically alpha-linolenic acid (18:3 n-3).

Main Results:

  • Probiotic supplementation reduced alpha-linolenic acid proportions in plasma neutral lipids.
  • Lactobacillus GG did not alter alpha-linolenic acid in phospholipids.
  • Bifidobacterium Bb-12 significantly increased alpha-linolenic acid proportions in phospholipids (0.13 ± 0.03 to 0.24 ± 0.03, P = 0.002).

Conclusions:

  • Probiotic interventions can influence the absorption and utilization of dietary PUFAs in infants.
  • Specific probiotic strains may have differential effects on fatty acid metabolism.
  • These findings highlight potential physiological interactions between probiotics and dietary PUFAs in the context of infant health.

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Probiotics01:22

Probiotics

Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
Anatomy of the Intestines01:53

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.Small IntestinesThe small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small intestine...
Dysbiosis of the Gut Microbiota01:18

Dysbiosis of the Gut Microbiota

The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
